Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a fire fighting water intake device. Background Art

[0002] "Firefighting" is a general term for eliminating hidden dangers, preventing and solving man-made, natural and accidental disasters encountered by people in the process of life, work and study. In the process of firefighting and rescue, in some old urban areas, urban villages and other locations, even if outdoor fire hydrants are installed on both sides of the road, due to narrow roads, space height restrictions, occupying the road for business, illegal parking and other reasons, fire trucks may not be able to directly reach or approach the fire scene in time. Therefore, they cannot directly use the outdoor fire hydrants near the fire scene to discharge water to extinguish the fire. At this time, a hand-lifted motor pump is needed to fetch water nearby for fire extinguishing. When the motor pump is used, water needs to enter its interior through a water inlet and then enter the water pipe. However, during the use of the current water inlets, most of the water inlets are directly placed in the water. Due to the complexity of the water source environment near the fire scene, there will be garbage and mud in the water source, which may cause the water inlet to be blocked, thereby affecting the water inlet efficiency. Therefore, we proposed a fire-fighting water inlet to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a fire-fighting water inlet device proposed by an embodiment of the utility model comprises a mounting tube 1, the inner wall of the mounting tube 1 is provided with a connecting thread, the bottom end of the mounting tube 1 is rotatably connected with a connecting tube 2, a filter cartridge 3 is installed at the bottom end of the connecting tube 2, two annular plates 14 are fixed to the outer wall of the filter cartridge 3, an arc plate 15 is fixed in an annular array between the two annular plates 14, which can play an auxiliary protective role for the filter cartridge 3, so as to reduce the floating impurities in the water adhering to the surface of the filter cartridge 3, a fixing ring 4 is fixed to the surface of the mounting tube 1, and four supporting rods 5 are rotatably connected to the outer wall of the fixing ring 4 through a pin shaft, annular air bags 6 are placed on the top of the four supporting rods 5, a sealing head is provided on the annular air bag 6, a storage assembly 7 for folding the supporting rods 5 is provided on the surface of the connecting tube 2, and the tops of the four supporting rods 5 are An elastic band 8 is fixed, and a clamping block 9 is fixed at the other end of the elastic band 8. A limiting hole 10 is fixed on the top of the clamping block 9. A limiting component 11 that engages with the limiting hole 10 is provided on the top of the support rod 5. When using this fire-fighting water inlet, the mounting tube 1 can be connected and fixed with one end of the water pipe, and then the clamping block 9 at one end of the elastic band 8 can be respectively inserted into the corresponding limiting component 11. At this time, the limiting fixation of the annular airbag 6 can be completed, and then the water inlet can be placed in the water source as a whole. Under the action of the annular airbag 6, it can float on the water surface, and the connecting pipe 2 and the filter cartridge 3 will penetrate into the water, thereby realizing the water inlet operation. When the water inlet is used, the elastic band 8 can be operated to release the limiting of the annular airbag 6, and then the annular airbag 6 can be removed and deflated and placed separately with the mounting tube 1 and the connecting tube 2.

[0024] like Figure 1 and Figure 2 As shown, in some embodiments, the storage component 7 includes a moving ring 701 threadedly connected to the surface of the connecting tube 2, and the surface of the moving ring 701 is rotatably connected to four connecting rods 702 through a pin shaft, and a connecting block 703 is fixed to the bottom of the support rod 5. The other end of the connecting rod 702 is rotatably connected to the corresponding connecting block 703 through a pin shaft, and a rotating block 704 is fixed to the surface of the connecting tube 2. When the support rod 5 needs to be stored, the connecting tube 2 is driven to rotate by rotating the rotating block 704. After the connecting tube 2 rotates, the moving ring 701 will be driven to move downward. Because the top of the connecting block 703 is fixedly connected to the corresponding support rod 5, with the cooperation of the connecting rod 702, the support rod 5 can be rotated downward for storage. When the support rod 5 is opened, it is only necessary to rotate the connecting tube 2 in the opposite direction.

[0025] like Figure 1 and Figure 4As shown, in some embodiments, the limit assembly 11 includes a limit block 1101 fixed to the top of the support rod 5, and a slot 1102 adapted to the card block 9 is opened on the top of the limit block 1101. Two springs 1103 are fixed inside the limit block 1101. The springs 1103 are all made of stainless steel. Stainless steel has corrosion resistance to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts, thereby extending the service life of the springs 1103. A movable plate 1104 is fixed to one end of the two springs 1103, and a protrusion 1105 adapted to the limit hole 10 is fixed to one side wall of the movable plate 1104. Two push rods 1106 are fixed to one side wall of the movable plate 1104. The other ends of the two push rods 1106 slide through the limit block 1101 and extend to the outside thereof and are fixed with a push plate 1107. It is necessary to move the card block 9 When inserted into the interior of the limit block 1101, the push plate 1107 can be pressed. After the push plate 1107 moves, the push rod 1106 can push the movable plate 1104 to move. After the movable plate 1104 moves, the two springs 1103 will be in a compressed state. At this time, the card block 9 can be inserted into the interior of the limit block 1101 through the slot 1102. When the card block 9 is inserted into the interior of the limit block 1101, the limit hole 10 will correspond to the protrusion 1105, and then the push plate 1107 is released. At this time, under the reset force of the two compressed springs 1103, the movable plate 1104 will be reset and will drive the protrusion 1105 to be inserted into the interior of the limit hole 10, thereby fixing the card block 9. When the card block 9 needs to be taken out, repeat the above operation. When the protrusion 1105 is separated from the limit hole 10, the card block 9 can be taken out from the inside of the slot 1102.

[0026] like Figure 3 As shown, in some embodiments, a rotating ring 12 is fixed to the bottom of the mounting tube 1, and a ring rail 13 compatible with the rotating ring 12 is fixed to the top of the connecting tube 2, so that the connecting tube 2 can rotate without being separated from the mounting tube 1, so that the storage assembly 7 can be driven after the connecting tube 2 is rotated later.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
